On Drew Pritchard's "Salvage Hunter Classic Cars" recently, they did a refit of an MGC interior. They used a specialist upholsterer, and interestingly he said that the stitching and pleating had to be done the opposite way on the drivers, and passengers seat. This was because as you slide into the seat, it pulls on the stitching and if it's not done in the right alignment it will pull, and wear the leather prematurely.
